Opening files with scripts

ChrisFontenot13 wrote on 12/1/2004, 2:31 PM

How do you get vegas to open a file (mpg) using JS in 4.0e?
I'm trying to write a quick "trimmer" than renders to a temp file, closes the project, deletes the formerly opened file, renames the temp to the name of the formerly opened file, and then opens the file. The open command is all I am missing.

I was wondering if there was any way to get vegas to grab the "next file in line" in a directory? Or to have it pop to the "Open" screen? Opening everything on a single timeline isn't practical for me, and I often have fifteen or so videos to run through in an afternoon... any ideas?

Boy, is my face red.

Vegas.OpenProject();

Got the trimmer written if anyone's interested. (4.0e)

Still don't know how to read in all files in a directory, but I'm sure someone out there knows something.

System.IO.Directory.GetFiles("C:\");

will read all of the files in a directory and return them as a string array.

The .Net Framework SDK documentation has a lot of info about the various .Net classes.

Thanks for the reference!

Ok, I'm digging through the .Net Documentation, but I can't figure out how to step through each instance of the items to retreive individual videos stored in the string array. I'm VERY new to all this.

You might want to read the JScript reference material in the .Net documentation. It is in the contents under Reference, then Compiler and Language Reference, then JScript. Look for the "for...in" statement.

But, I will give you the answer here. The quick way is:

var files = Directory.GetFiles("C:\");
for (var file in files)
{
Vegas.OpenProject(file);
}

Wow! I've gotten that script off the ground, and very well. This is my best chunk of code to date. Thanks for the references.

I would like to see the script. Would you mind posting the code? Thanks.

This is the first script I've written myself. It's a bit of a hack, but it works. It will require some editing to personalize (I'm hoping to improve its portability). We often read 30 or 40 videos in at a time, then open each in turn and save a few jpgs from it using (filename + "P00.jpg"). I wrote this to check for the first one that does not have at least one Jpeg saved from it and open that one.

*	If there is no associated JPG, it opens the current MPG.

*

*	It is easily adaptable into a function that returns the
